These topics are usually covered in grades 4-6.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003eThe book begins with 4th grade topics, starting out with the concept of \u003cstrong\u003edivisibility and the common divisibility rules\u003c\/strong\u003e. The lesson \u003cem\u003ePrime Numbers \u003c\/em\u003ebrings out the concept of a prime number as one that is only divisible by 1 and by itself. Armed with the knowledge about divisibility, students now learn how to find factors of a given two-digit number in the lesson \u003cem\u003eFinding Factors\u003c\/em\u003e.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003eThe following lesson, \u003cem\u003e Primes and Finding Factors\u003c\/em\u003e, is a review lesson about factors, primes, and divisibility rules, originally intended for beginning of 5th grade. You can use it as a review of the first four lessons of this book, or for students that have some knowledge of these topics already.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003eThe next two lessons delve into \u003cstrong\u003eprime factorization\u003c\/strong\u003e using a factor tree. The first lesson on the topic only uses two-digit numbers. In the latter, students are introduced the sieve of Eratosthenes and they factorize three-digit and larger numbers.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003eThe last topics in the book are \u003cstrong\u003ethe greatest common factor (GCF), the least common multiple (LCM), and factoring sums\u003c\/strong\u003e, intended mainly for 6th grade. Factoring sums means writing a sum such as 42 + 18 as 6(7 + 3). We first find a common factor of 42 and 18 (which is 6), and use that to factorize the sum. The lesson only deals with numeric examples, but it is actually preparing students for algebra, where the same process is done with variables; for example \u003cem\u003ex\u003c\/em\u003e\u003csup\u003e2\u003c\/sup\u003e + 2\u003cem\u003ex\u003c\/em\u003e is factored as \u003cem\u003ex\u003c\/em\u003e(\u003cem\u003ex\u003c\/em\u003e + 2).\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003eThe book ends in a review lesson.
